<div class="jive-rendered-content"><p>I am playing around jBPM 5.3.0.Final in pass weeks, I am working on a simple demo that jBPM to start an external ETL process by JMS. When the external process are done, a JMS message is sent back to the server to feedback the result and finish the process in jBPM. I am using jBPM-console to start the process.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I have developed my WorkItemHandler to send the JMS message, and I didn't call the workItemMgr.completeWorkItem(workItem.getId(), map) ; in my executeWorkItem() method. I am expecting this would keep the process in wait state and the process would be completed by a MDB listening the response JMS message from external process.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The problem I have now is I am not able to restore the session in my MDB to complete the process. From other threads I get the idea to call JPAKnowledgeService.loadStatefulKnowledgeSession() with the session id  and then complete the work item by ksession.getWorkItemManager().completeWorkItem(). However, from my WorkItemHandler executeWorkItem(WorkItem workItem, WorkItemManager workItemMgr) I am not able to get the session Id, also, I registered my handler through jBPM-console, it seems like that I am not able to pass the session id from the constructor as well.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>So can some experts give me some advise on how to get the session id and how to complete the jBPM task in my MDB ? And what is the best way to have external process to acknowledge jBPM for task completion ? Thanks!</p></div>
